This post includes R code and materials from my Computational Social Science course at Rutgers University. The course offers theoretical discussion and hands-on training using R. It is a doctoral seminar offering a gentle introduction to computational methods both for people with some previous experience in coding, and for those who [...]
This is a comprehensive tutorial on network visualization with R. It covers data input and formats, visualization basics, parameters and layouts for one-mode and bipartite graphs; dealing with multiplex links, interactive and animated visualization for longitudinal networks; and visualizing networks on geographic maps. To follow the tutorial, download the code and [...]
More details to follow, but for now: workshop materials from Sunbelt 2016.

In the next few months, I will be running several network visualization workshops using R and Gephi at Sunbelt 2016 (Newport Beach, CA) and Political Networks (St. Louis, MO). The descriptions follow below - if you are going to one of the conferences, do stop by! By popular demand, the workshops [...]
Get the tutorial PDF and code, or download on GithHub. A more recent tutorial covering network basics with R and igraph is available here. If you find the materials useful, please cite them in your work – this helps me make the case that open publishing of digital materials like this [...]
A new Politico post produced by our lab examines the mentions of countries around the globe in congressional documents. We look at the frequency of country mentions and co-occurrence. These numbers were extracted from political statements provided by VoteSmart. Here we post the data we used for those visualizations. The files [...]
David Lazer, Oren Tsur, and I recently took a look at the use of the term "coal" in documents produced by members of the US Congress. Some numbers and visualizations based on this were published by Politico. Here, we post the data behind the network map of term co-occurrence in coal-related [...]
If you are interested in analyzing the deleted tweets of politicians, my new R package PolitwoopsR is available on GitHub. Also see this R script examining deleted tweets. [Update 15/04/02] If you were brought here by a Dean Richards Twitter bot, read this. A few days ago I published [...]
Politicians Descriptive Party States URLs Terms/Tags Sentiment Term net [UPDATE 15/03/30] Check out this follow-up post to get the R code used to extract and clean the Politwoops & Twitter data. A package that automates the data collection is now available on GitHub: PolitwoopsR. For some months now, I've been playing [...]
Facebook Network: Gephi Facebook Network: igraph Facebook Network: qgraph [Update April 26 2o14] Esteban Moro reminded me that there's no need to manually rescale igraph layouts now - one can use layout.norm() instead (script updated accordingly). Hugle [...]
In the last few months, I've been working with a great team of scholars putting together a study commissioned by the FCC. The project provides a critical review of existing research on the information needs of communities in the US. Major points include defining individual and community critical needs, examining the [...]
